<p>Hi there,</p>
<p>I wonder what happened to <code>-Cno-integrated-as</code>  option? The only thing I could find is <a href="https://github.com/rust-lang/rust/pull/70345">https://github.com/rust-lang/rust/pull/70345</a>.</p>
<p>However, I need this option to switch to GNU <code>as</code> on some <code>mipsel</code> devices that have issues with<code>ll/sc</code> which LLVM <code>as</code> does not currently provide a fix.</p>
<p>Is there any way to use it on a stable channel Rust compiler? If not, is there any suggestion on how to restore this functionality?</p>
<p>Thanks</p>

<p>probably a bad idea: using <code>--emit</code> to generate the asm and then running your preferred assembler over that? :^)</p>
